How to deal with SAT agreements

Can anyone advise on how to deal SAT agreements?  

I am currently looking to purchase at (Scottish) auction and have noticed that many of the proprieties have sitting tenants on SAT agreements. This is reflected in the price and therefore the properties are normally heavily discounted from area comparables. My limited understanding of SAT agreements is that this makes it very difficult to evict the tenant which in turn devalues the property. The SAT agreements are always outdated, achieving way below market value with regard to rental income.

I am looking to find ways to overcome these problems so that I can take advantage of the opportunity rather than let it pass as most other investors do. Most of these properties do not sell in the room.

Many thanks in advance for everyone’s thoughts.
